Psalm 122:6 King James Version (KJV)6 Pray for the peace of Jerusalem: they shall prosper that love thee.

The aforementioned verse was not a commandment of God, but rather a request of David concerning Israel during their season of conflict. God, in His mercy granted David’s request. He gave Israel a time of rest contingent upon their obedience to Him. God’s sure mercy towards David that even, though Israel did not fully obey God, He would give them rest for David’s sake for as long as Solomon lived. God informed David of His divine favor towards him:

1 Chronicles 22:1-9 King James Version (KJV)1 Then David said, This is the house of the Lord God, and this is the altar of the burnt offering for Israel.2 And David commanded to gather together the strangers that were in the land of Israel; and he set masons to hew wrought stones to build the house of God.3 And David prepared iron in abundance for the nails for the doors of the gates, and for the joinings; and brass in abundance without weight;4 Also cedar trees in abundance: for the Zidonians and they of Tyre brought much cedar wood to David.5 And David said, Solomon my son is young and tender, and the house that is to be builded for the Lord must be exceeding magnifical, of fame and of glory throughout all countries: I will therefore now make preparation for it. So David prepared abundantly before his death.6 Then he called for Solomon his son, and charged him to build an house for the Lord God of Israel.7 And David said to Solomon, My son, as for me, it was in my mind to build an house unto the name of the Lord my God:8 But the word of the Lord came to me, saying, Thou hast shed blood abundantly, and hast made great wars: thou shalt not build an house unto my name, because thou hast shed much blood upon the earth in my sight.9 Behold, a son shall be born to thee, who shall be a man of rest; and I will give him rest from all his enemies round about: for his name shall be Solomon, and I will give peace and quietness unto Israel in his days.

Solomon acknowledged the fulfilment of David’s prayer that Jerusalem was at peace:

1 Kings 5:1-4 King James Version (KJV)1 And Hiram king of Tyre sent his servants unto Solomon; for he had heard that they had anointed him king in the room of his father: for Hiram was ever a lover of David.2 And Solomon sent to Hiram, saying,3 Thou knowest how that David my father could not build an house unto the name of the Lord his God for the wars which were about him on every side, until the Lord put them under the soles of his feet.4 But now the Lord my God hath given me rest on every side, so that there is neither adversary nor evil occurrent.

Never-the-less, Solomon disobeyed God, but God kept His promise to David. After the death of Solomon, there was no lasting peace:

1 Kings 11:1-12 King James Version (KJV)1 But king Solomon loved many strange women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Zidonians, and Hittites:2 Of the nations concerning which the LORD said unto the children of Israel, Ye shall not go in to them, neither shall they come in unto you: for surely they will turn away your heart after their gods: Solomon clave unto these in love.3 And he had seven hundred wives, princesses, and three hundred concubines: and his wives turned away his heart.4 For it came to pass, when Solomon was old, that his wives turned away his heart after other gods: and his heart was not perfect with the LORD his God, as was the heart of David his father.5 For Solomon went after Ashtoreth the goddess of the Zidonians, and after Milcom the abomination of the Ammonites.6 And Solomon did evil in the sight of the LORD, and went not fully after the LORD, as did David his father.7 Then did Solomon build an high place for Chemosh, the abomination of Moab, in the hill that is before Jerusalem, and for Molech, the abomination of the children of Ammon.8 And likewise did he for all his strange wives, which burnt incense and sacrificed unto their gods.9 And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel, which had appeared unto him twice,10 And had commanded him concerning this thing, that he should not go after other gods: but he kept not that which the LORD commanded.11 Wherefore the LORD said unto Solomon, Forasmuch as this is done of thee, and thou hast not kept my covenant and my statutes, which I have commanded thee, I will surely rend the kingdom from thee, and will give it to thy servant.12 Notwithstanding in thy days I will not do it for David thy father's sake: but I will rend it out of the hand of thy son.

You see, true peace can only come from Jesus:

Isaiah 9:6 King James Version (KJV)6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.

John 14:27 King James Version (KJV)27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.

Jesus is peace personified. We can only be partakers of that peace if we recognize Jesus as the Lord’s Salvation:

Luke 2:25-30 King James Version (KJV)25 And, behold, there was a man in Jerusalem, whose name was Simeon; and the same man was just and devout, waiting for the consolation of Israel: and the Holy Ghost was upon him.26 And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord's Christ.27 And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law,28 Then took he him up in his arms, and blessed God, and said,29 Lord, now lettest thou thy servant depart in peace, according to thy word:30 For mine eyes have seen thy salvation,Furthermore, we must publicly acknowledge that Jesus is the Lord’s salvation to us if we submit to Him:

John 3:16-17 King James Version (KJV)16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.

My prayer for Israel is the desire that Paul has for all Israel, that they might be saved because it is through salvation they will have access to Peace personified:

Romans 10:1-3 King James Version (KJV)1 Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.2 For I bear them record that they have a zeal of God, but not according to knowledge.3 For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.

My prayer is not for Israel alone, but for every Nation and all men everywhere:

1 Timothy 2:1-3 King James Version (KJV)1 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men;2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty.3 For this is good and acceptable in the sight of God our Saviour;

You see, God has already promised that there would be peace in Jerusalem and the Nations, if we as collective members of the Body of Christ; followers of Jesus would submit to Him:

2 Chronicles 7:14 King James Version (KJV)14 If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
